HARBAUGH AND CHARLES JACOB SMITH, OF ASHLAND, 01110, AssI'GNons To THE ELITEMANUFAGTURING COMPANY, OF ASHLAND, OHIO, A CORPORATION OF OHIO Application filed May 18,

This invention pertains to an improvement in pushing and pulling implements, and conthe present tool may be used to spring or I hold the fenders of an automobile in place; to straighten crooked fenders; to remove dents in the body or a fender; to remove deformed wheel housings; to straighten doors or a twisted frame or body, and so forth.

In theaccompanying drawing, Fig. 1 is a side elevation of the tool on a reduced scale,

and Fig. 2 a side elevation and sectional view thereof at right angles to Fig. 1. Figs. 3, 4, and 5,-are side elevations of the three interchangeable heads for the tool. Fig. 6 is a side elevation of an adjustable nut and bracket attached to the screw member of the tool, and

- Fig. 7 is a. sectional view thereof on line 77 of Fig. 6. Fig. 8 is a front view of the bracket shown in Fig. 6. Fig. 9 is a plan view of the opened coupling member attachedto the extensible member of the tool, and Fig. 10 a transversal sectional view. of the coupling member in closed position. i

The tool or instrument comprises a relatively long screw shaft 2 rigidly connected to a plate 3. As shown, one end of screw shaft 2 is reduced in diameter and fastened by a set screw 4 within a socket or boss 5 on plate 3,. which plate may be round, square or of other shape. An extensible member 6, in the form of a pipe or tube, is sleeved over the opposite end of screw shaft 2, and a coupling member or split nut is screw-connectedwith one end of this tube. Coupling member-7 includes. a smoothly-finished semi-cylindrical extension (1 and a screw-threaded semicylindrical section b hinged thereto. A pivoted clamping screw and nut a is provided to fasten the hinged section to the extension, so that the screwathreads on the hinged section will be positively engaged with the screwthreads on shaft 2, therebypermitting the .-tube or extensible member 6 to be screwed lengthwise on the shaft to either increase or decrease the working range of the tool. A more ra id adjustment and setting may be obtain by releasing the hinged section and As shown,

- also PUSHING PULLING IMPLEMENT 1929. Serial No. 364,210. v disengaging its screw-threads on shaft; 2, which permits the tube 6to slide freely lengthwise of shaft 2. In other Words, the split nut 7 permits uncoupling of the shaft and tube f or quick adjustment.

The outer end of, extensible member 6 is screw-threaded to permit different-shaped headsto be detachably connected therewith. Thus either a round or crescent-shaped head.

8 (as delineated in Figs. 1 and 2) or a curved, flat or angular head 9, l0, and 11, respectively, (as shown in Figs. 3 to 5) inclusive, may be attached to member 6 to'fit any part of a fender, frame, or body of corresponding shape and. form.

A yoke 14 and a revoluhle nut 15 are coupled together and sleeved on screw shaft 2 to proyide means for imparting pushing and pulling movements to the object or part to be repaired or operated upon, the yoke being free to slide on shaft 2 and the nut being screw-connected therewith to move or shift the yoke in either direction relatively to plate 3 on shaft 2 or head 8 on extensible member 6. Yoke 14 includes a lateral arm 16 having an angular or hook-shaped extremity 17 adapted to hook over or press against ail object when plate 3 and head 8 are engaged with or bear against different parts or places respectively,

the nut, and gear 19 being rotatably supported by a stud shaft 12 at one side of yoke 14. Operatmg gear 19 is adapted to be rotated by a crank handle 20, or by an oscillatory lever 21. having a reversible spring-pressed pawl 22 engagea'ble with the teeth on gear 19. lever 21-.includes a round hub 23 sleeved on stud shaft 12, and'the operating gear 19 is sleeved over place by a washer 24.

To extend the usefulness of the tool, we provide a supplementary bracket 25 adapted to be clamped upon screw shaft 2 to co act with operations.-

Bracket 25 has a divided hub 26 which is screw-threaded to interlock with the screwthis hub and held in yoke 14 in pushing and pulling y an automobile for repair purposes;

threads on shaft 2, and a bin ed thumb-screw and nut 27 serves to clamp e divided parts of the hub'tightly upon the shaft. Bracket may be rotated around shaft 2 to place its 5 bifurcated or forked arm 28 opposite or in line with arm 16 on yoke 14, and bein detachable from shaft=2 the positions 0% the bracket 25 may also be reversed, that is, the

forked arm 28 may be projected toward yoke 1 Her away from it. Yoke 14 being also rotatable on shaft 2 its arm 16 may be projected in any direction radially of the shaft. Thus, in Fig. 1, we show yoke 14 and supplemental bracket 25 (in full and dotted lines 15 respectively) projecting in the same direction from shaft 2. Obviously, these parts may be rotated to project in any direction, than as delineated, and the tool may be used in different ways and applied to many plac i shon us the forked arm 28 may be seated against the; hub of a wheel, or against a shaft or earn r of a frame, and 'arm 16 employed to press I against or pull another part, such as a housfender or the like, either to remove, re-

it. The forked arm' 28, and

ing, place or repair head 8 may alsobe used to anchor or support signatures.
